The paper presents the possibilities of using the methods of the synergetic
approach for the synthesis of the control law for nonlinear dynamic objects. To impart robust
properties to the control law, it is proposed to apply the principle of integral adaptation, which
makes it possible to compensate for the influence of external and parametric disturbances. The
implementation of the synergetic control law is carried out when constructing the analytical
design of aggregated controllers, which provide the asymptotic stability of the control system for
nonlinear dynamic objects. To ensure technological invariance, the principle of synergetic control
is proposed. At the same time, an extended dynamic model of the system was formulated,
including external and internal perturbations. To determine the trajectory of movement of
variable coordinates, a functional relationship of the AKAR method was compiled. The application
of the method of analytical design of aggregated controllers makes it possible to eliminate the
need for the synthesis of the observer of states, due to the presence in it of the possibility of
prompt evaluation of external and internal disturbances. The main idea of the new approach is to
use a single high-order perturbation model, consisting of series-connected integrators, instead of
separate models for each perturbation separately. The proposed technique is confirmed by
examples of digital modeling and the effectiveness of the proposed approach to the problems of
synthesis of a nonlinear control system for dynamic objects is shown, which ensures the stability
of the control system and compensates for unmeasured and external disturbances.
